Alpha globulins are a group of
globular proteins in
plasma
Plasma or plasm may refer to:
Science
* Plasma (physics), one of the four fundamental states of matter
* Plasma (mineral), a green translucent silica mineral
* Quark–gluon plasma, a state of matter in quantum chromodynamics

In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a base (chemistry), basic, ionic compound, ionic salt (chemistry), salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as ...
or electrically charged solutions. They inhibit certain blood
proteases and show significant inhibitor activity.
The alpha globulins typically have molecular weights of around 93 kDa.
Examples
Alpha globulins include certain hormones, proteins that transport hormones, and other compounds, including
prothrombin and
HDL.
